Custom AutoSound USA-740 Radio with Bluetooth
The Custom AutoSound USA-740 keeps the classic look Custom AutoSound is known for and adds the features most drivers want today, starting with built-in Bluetooth. You can stream music and take hands-free calls from your phone, and the included remote microphone mounts where it picks up your voice. Like the rest of the USA series, the USA-740 is built to fit the stock dash with no modifications.

Why Choose the USA-740
The USA-740 is the most complete radio in the USA series. Compared with the USA-630, it has Bluetooth built in instead of as a BLUKIT add-on, plus more presets, a front aux jack, FLAC and WAV support, a color-matched display and a dedicated subwoofer output. Compared with the USA-230, it adds USB, RDS, Bluetooth and 100 more watts of peak power. If you plan to add amplifiers or a subwoofer, the hi-volt pre-outs give a cleaner signal to work with.

How to Choose
Choose the USA-740 if you want Bluetooth without extra boxes, plan to add an amp or subwoofer, or want the display to match your dash lights. If you only need radio and aux, the USA-230 saves money. If you'd rather have a true working slidebar dial up front, look at the Slidebar radio.
Before You Order

- Speakers: a stereo radio needs at least two speaker channels. If your car came with one mono dash speaker, see our classic car speakers and the speakers and wiring guide.
- Warranty: Custom AutoSound backs its radios with a limited warranty of 2 years on parts and 1 year on labor. See Warranty & What's Included.
- Not sure it fits? Use the year/make/model search at the top of any page, or call us at 844-802-4499. If your car isn't listed, Custom AutoSound can often build a radio to your dash dimensions; custom builds carry a surcharge and are not refundable.
